I bought one of these and while cool at the beginning, the battery is horrible. I can’t even run the flashlight for more than 15 or 20 minutes and then the battery dies. I don’t see how it would have enough power to incapacitate someone. Of course, I don’t have the balls to try it on myself. 
Maybe it came with a wanky cell. Is it an 18650? They’re cheap or rip one out o discarded laptop for free.
Bought one of these a few months back when they offered it. While it was cool at first, it only lasted for about a month and a half before the stun gun just completely crapped the bed. Flashlight works fine though.
This has a limited lifetime warranty with the manufacturer. Make sure you contact them.
Yes, a common side effect of the stun gun is defecation, which if done in bed would leave quite a mess. (Much worse than Earnie eating cookies in bed. I believe Bert would care much more if Earnie defecated on him.) CHEERS!
